Main jets up to 122.5 and pilots up just one size (both carbs the same).
I did have a couple of shims fitted under the needles, but took them out again as the 1/4 - 1/2 throttle was a bit rich.
No other mods apart from setting pilot screw 3 turns out (only a rough guide as bike to bike & altitude will effect this).

Raising the needles make the mix richer - effecting 1/4 - 3/4 throttle range (approx) - it isn't necessarily related to rpm !

The pilot jets defo need to be upped 1 x size to help the poor part throttle running/spit back & slow warm-up.

To ensure the air:fuel ratio is not overly lean at over 1/2 throttle opening, try upping the main jet a bit.... leave the needles until you've done this first.
